Three PhD positions at EPFL, VUB and UGent on the testing and analysis of thick adhesive joints in large wind turbine blades

Wind energy is an important source of renewable energy with a substantial increase in the coming years. The performance of wind turbine blades is essential to provide the needed power output and guarantee a stable and long-term reliability of the wind turbines.

Since wind turbine blades are held together by adhesive joints, these form a crucial load carrying part in the blade assembly. The main objective of the proposed research is a new combined numerical and experimental approach for the development, testing and analysis of thick adhesive joints in large wind turbine blades, and by extension in other large civil engineering structures such as composite ship structures, composite bridges, composite locks, etc.

The project is funded by the Swiss National Science Foundation (SNSF) and by the Fund for Scientific Research – Flanders (FWO-Vlaanderen) to form a collaboration between EPFL (Lausanne, Switzerland), Ghent University (UGent), and the Free University of Brussels (VUB). The three PhD student at EPFL, VUB and Ghent will closely work together.

Skills/Qualifications

The work at EPFL and VUB entails an experimental campaign to obtain data from realistic quasi-static and fatigue loading conditions on thick epoxy joints. The experimental program will focus on understanding the loading effects including biaxial stress states on the quasi-static and the fatigue behavior of structural joints. A commercial adhesive will be used as a reference while research will be conducted, in parallel and guided by the modelling/experimental results, on adhesive materials development, to reach an optimal combination of resin stiffness, toughness and viscoelastic properties. This will include exploration of the use of second phases and charges, compatible with the current processing techniques (high viscosity at rest and moderate upon curing), which increase damage tolerance in the specific conditions of mixed-mode and fatigue loading.

Over the last years, UGent-MMS has developed the stand-alone BladeMesher software for generating finite element models of large wind turbine blades. The software reads in the material data and airfoil data of the wind turbine blade, and automatically constructs the geometry and finite element mesh for the blade. The BladeMesher software is programmed in the Python language and counts more than 30,000 lines of code.

In this project, the BladeMesher software is further developed to include additional features, such as detailed modelling of adhesive joints (with cohesive elements), implementing support for more advanced finite element types (quadratic and multi-layer solid and solid shell elements) and user-friendly Graphical User Interface (GUI).
